与众多学科一样,化学具有其自身的特色。化学是一门典型的理论与实践紧密结合的现代科学。它不仅是由一系列概念、法则和定理组成的具有较强准确性和逻辑行的理论体系,更是一门具有较强实践性的应用科学。所以,学好化学不但要求学生具有接受知识的学习能力,还应具有应用知识的实践能力。然而这些能力培养与提高的主要场所便是课堂,因此,如何提高课堂效率,将有限的时间变换成无限的知识和能力成为 Like many disciplines, chemistry has its own characteristics. Chemistry is a typical modern science that combines theory with practice. It is not only a theoretical system composed of a series of concepts, rules and theorems, but also a relatively practical and practical application of science. Therefore, learning chemistry not only requires students to have the ability to learn the knowledge, but also should have the practical ability to apply knowledge. However, the main venue for the cultivation and improvement of these abilities is the classroom. Therefore, how to improve classroom efficiency and transform limited time into unlimited knowledge and ability to become
